  2. Hall-type theorems for hypergraphs - Wikipedia

    en.wikipedia.org/wiki/Hall-type_theorems_for...

    Any tripartite hypergraph (X 1 + X 2 + Y, E) in which | Y | = 2n – 1, the degree of each vertex y in Y is n, and the neighbor-set of y is a matching, has a matching of size n. [23] The 2n – 1 is the best possible: if | Y | = 2n – 2, then the maximum matching may be of size n-1.

    [43] [2] [44] [45] By 2012, split spectrum amplitude decorrelation was shown to be effective at increasing SNR and decreasing motion artefacts. [37] Commercial OCT-A devices also emerged around this time, beginning with the OptoVue AngioVue in 2014 (SD-OCT) and the Topcon Atlantis/Triton soon after (SS-OCT). [43]

    The first demonstrations of in vivo OCT imaging quickly followed. [3] [4] [5] The first US patents on OCT by the MIT/Harvard group described a time-domain OCT (TD-OCT) system. [6] [7] These patents were licensed by Zeiss and formed the basis of the first generations of OCT products until 2006.

    en.wikipedia.org/wiki/Octree

    The use of octrees for 3D computer graphics was pioneered by Donald Meagher at Rensselaer Polytechnic Institute, described in a 1980 report "Octree Encoding: A New Technique for the Representation, Manipulation and Display of Arbitrary 3-D Objects by Computer", [1] for which he holds a 1995 patent (with a 1984 priority date) "High-speed image generation of complex solid objects using octree ...

    For a bipartite graph G with def(G;X) = 0, the number sur(G;X) is the largest integer s satisfying the following property for every vertex x in X: if we add s new vertices to X and connect them to the vertices in N G (x), the resulting graph has a non-negative surplus. [2]: Thm.1.3.6

    The first intravascular in vivo use in a preclinical model was reported in 1994 [6] and first in human, clinical imaging in 2003. [7] The first OCT imaging catheter and system was commercialized by LightLab Imaging, Inc., a company based in Massachusetts formed following a technology transfer in 1997 from Fujimoto's lab (MIT).

    Let P 1 = (X 1:Y 1:Z 1) and P 2 = (X 2:Y 2:Z 2) be two points distinct to θ. Assuming that Z 1 = Z 2 = 1 then the algorithm is given by: A = X 1 Y 2. B = Y 1 X 2. X 3 = B Y 1-Y 2 A Y 3 = X 1 A-B X 2 Z 3 = Y 2 X 2-X 1 Y 1. The cost needed is 8 multiplications and 3 additions readdition cost of 7 multiplications and 3 additions, depending on the ...
